 Use of OB-1


A small-molecule inhibitor of STOML3 oligomerization that reverses pathological mechanical hypersensitivity in vivo; effectively inhibits the self-association of stomatin, STOML1 and STOML2 at 2 uM, but not podocin; reversibly reduces the sensitivity of mechanically gated currents in sensory neurons and silence mechanoreceptors in vivo; also reversibly attenuates fine touch perception in normal mice, reverses pathological mechanical hypersensitivity.
